Gate Stack Engineering for High-Mobility and Low-Noise SiMOS Quantum Devices
Md. Mamunur Rahman, Ensar Vahapoglu, Kok Wai Chan +16
We systematically investigate the interplay between materials engineering, quantum transport, and low-frequency charge noise in silicon metal--oxide--semiconductor (SiMOS) quantum…
Qudit Designs and Where to Find Them
Namit Anand, Jeffrey Marshall, Jason Saied +2
Unitary t-designs are some of the most versatile tools in quantum information theory. Their applications range from randomized benchmarking and shadow tomography, to more fundament…
Maximizing the nondemolition nature of a quantum measurement via an adaptive readout protocol
Arjen Vaartjes, Rocky Yue Su, Laura A. O'Neill +15
Quantum error correction (QEC) requires non-invasive measurements for fault tolerant quantum computing. Deviations from ideal quantum non-demolition (QND) measurements can disturb…
Coupling a Ge nuclear spin to an electrostatically defined quantum dot
Paul Steinacker, Gauri Goenka, Rocky Yue Su +17
Single nuclear spins in silicon are a promising resource for quantum technologies due to their long coherence times and excellent control fidelities. Qubits and qudits have been en…
Coherent all-optical control of the germanium vacancy in diamond
C. Adambukulam, J. A. Scott, S. Q. Lim +3
The germanium vacancy in diamond (GeV) is a promising candidate for color center based quantum networking. Yet, like for other group-IV vacancy defects in diamond, achieving fast,…
